---------------------------------引用--------------------------------------
Any existing applications that use the Cancel processing will need to modify their struts-config.xml to set the cancellable property for actions which require it.
In Struts 1.2.9 the <set-property> is used to set the cancellable property for an action....
<action path="/fooAction"
input="/foo.jsp"
validate="true">
<set-property property="cancellable" value="true"/>
<forward name="success" path="/bar.jsp"/>
</action>
From Struts 1.3.x a new cancellable attribute can be used....
<action path="/fooAction"
input="/foo.jsp"
validate="true"
cancellable="true">
<forward name="success" path="/bar.jsp"/>
</action>
In both Struts 1.2.9 and Struts 1.3.x an exception handler can be configured to handle the InvalidCancelException
<action path="/fooAction"
input="/foo.jsp"
validate="true"
cancellable="true">
<forward name="success" path="/bar.jsp"/>
<exception key="errors.cancel"
type="org.apache.struts.action.InvalidCancelException"
path="/foo.jsp"/>
</action>
---------------------------------------end-----------------------------------------------------
刚好我用的是struts�.2.9�br />
